    摘要： An optical connector-use adaptor which is so constituted as to prevent a laser beam from leaking to the outside and harming people when an optical connector plug is inserted or removed for optical connecting, which respectively has on one end side a housing unit opened at the tip end thereof and on the other end side a connection unit to which an optical component is connected, and which connects an optical connector plug, to be inserted into and connected with the housing unit, with the optical component with their optical axes aligned, characterized in that a super-elastic alloy-made shutter plate that is heat-treated to provide a flat-plate-memory feature without bending is mounted to a position closer to the opening end in the housing unit so as to erect from one wall surface up to a position for shielding the optical axis.
